Abstract
The ventilation device according to the invention includes a fan and an inverter. The fan comprises a rotary electrical machine and a wheel for setting an air flow into motion, integral with the rotary machine to set it in rotation. The inverter is connected to the rotary machine and, in one motor power mode of the ventilation device, is suitable for forming the supply current of the rotary machine. The inverter is suitable for being connected to a power supply network. The inverter is reversible and is, in a generating mode of the ventilation device, suitable for converting the electrical energy supplied by the rotary machine when it is driven mechanically by the wheel and injecting said converted electrical energy into the power supply network.
